Box Camera Photog
This photographer (among others) at the Capitolio in Havana use old box cameras circa 1900 to take your photo. The cost is one peso and they give you a positive and negative print, developed in the red can attached to the tripod leg.
The shutter is the lens cap. The photographer takes it off and puts it back a second later and the exposure is done. He then manually feeds the paper for the next shot. He'll photograph quite a few portraits before going into "development mode" where he develops the paper from the camera to produce the negative. He then takes the negative and photographs that, repeating the developing process to produce the positive. It worked quite well and was quite interesting to me to see the whole process. Well worth a peso!
